This paper proposes an ATM traffic management method that utilizes a deterministic source traffic descriptor, a deterministic Usage Parameter Control (UPC) algorithm and a conservative statistical bandwidth allocation method all of which were developed considering the Cell Delay Variation (CDV) typically experienced in ATM networks. For the source traffic descriptor, sliding time interval-type descriptors are proposed. A newly-structured UPC method which combines a sliding window-type circuit and a 2-phase credit window type circuit is proposed. The method is precise and accurate and requires only a small amount of hardware. The proposed parameter conversion method considers the CDV generated between User and UPC point. A bandwidth allocation method based on the worst clumping pattern and UPC output pattern is proposed. The network efficiency degradation caused by CDV is calculated. This traffic management method not only guarantees the QOS of all connections but also allows for large statistical multiplexing gains. The proposed method will, therefore, make it possible to create a more effective B-ISDN, one that can offer cost-effective broadband VBR services.
